Empty Multiple files contents
I would like to empty multiple files contents (without delete the file) which have similar name to begin with.

e.g.

log1.txt
log2.txt
log3.txt
log4.txt

I know cat /dev/null will do the job but that only apply to a single file. But when i tried cat /dev/null > {} \; that doesnt do anything at all.

This would fix your problem (I think)
try this thing;
Code:
find . -type f -name '*.txt' -print | while read i
do
  echo " " > $i
done

this will clear out the content of every *.txt found in "." (current directory)

It is not totally clear but a space I think...
hope it help..(smiley)
